problem light of the glow plugs fiat stilo 1.9 jtd

[gero]

hi all, I happened to have different fiat stilo lights glow plugs flashing,the controls that I have done are:controls all the glow plugs and harness arriving at the preheat current and ground to the ecu, tried another ecu,the current of the control unit, exit to the glow plugs, I don't know what to do

[jolidj]

if the combi control unit of the glow plugs novresti resolve. the basis that the ecu horsemanship, you can disable the ecu plugs and resolve .
nn and the way of the righteous but the electronics and also this :).

I changed the control unit of the spark plugs, but nothing to do

[booster]

have you done the test the glow plugs with the ammeter?

[ugoboss]

have you done the test the glow plugs with the ammeter?

usually the glow plugs are measured in ohms, not amps.

[booster]

the static test and the fai in ohms and sometimes stay screwed
the tester does not ? reliable for this test
at the limit, you can use a lamp light 5w or better 21w

then, if you have an ammeter
make a dynamic test connect the ammeter in series and feed the spark plugs one at a time
check the values of absorption if they are similar

[gero]

I did the test with the bulb and with the ohm tester

[booster]

at this point, in order to remove any doubt about the glow plugs you need to do the test again with the ammeter
the problem ? that usually ammeters, meters up to 10 amps and the spark plugs absorb approximately 12.5 amps
you have to find a suitable ammeter or a current clamp
(if the car ? your, and you don't have the tools, you can replace the 4 spark plugs)

if the problem ? still present, make sure the quick connectors on the glow plugs
and the wiring from the control unit pre-heating the engine control unit

try to measure the resistance of the glow plugs with a multimeter.... sometimes it happens that a spark plug to increase its value in the hom by decreasing its absorption......of course the ecu larileva burnt... the resistance should be intorono 0,6hom

[beppe.c]

also check the ecu dell (preheating control runs and welds).

[mar21]

but the glow plugs that have changed are of the same brand of the original?? to me ? happened cos? when I used to change my brand of glow plugs , probably why? a little bit, but change the resistor values

[gero]

the glow plugs have been checked and are the original ecu was changed with another

[progress]

if he has the filter diesel with the heater (don't know the engine and year of registration of the car) show the absorption could also be that makes you turn on the light the glow plugs seen that the resistance and enabled by the control unit glow plugs otherwise as colleagues controls the resistance of the glow plugs in ohms

[dom86]

evening to all I would try to make a diagnosis enveloped in the light of the glow plugs turn on x other symptoms then based on the year of the car to me ? 've cn a 2000 jtd lit the lamp of the glow plugs ? then it was a coil d injector

[autronica]

it often happens even when you do not change all 4 glow plugs new! if you replace only the ones that are interrupted, leaving one or more? candellette aparentemnete good (that light up), some times the damage... this applies to why? the calculation of the absorption occurs on the total amount of the 4 glow plugs. as it says in mar21, even to me ? success with a different brand, as already mentioned, the ohmic value, even if it could seem a little different it changed the total absorption...

[checchitotiralaleva]

An excellent tip to directly measure the absorption.

[ugoboss]

if he has the filter diesel with the heater (don't know the engine and year of registration of the car) show the absorption could also be that makes you turn on the light the glow plugs seen that the resistance and enabled by the control unit glow plugs otherwise as colleagues controls the resistance of the glow plugs in ohms

the problem of the heater of the fuel filter I mcapitato on a 147, I don't know if he has it, you should check.

[gero]

si c'? the heater in the fuel filter,but this is what problems it may bring

[ugoboss]

si c'? the heater in the fuel filter,but this is what problems it may bring

the heater of the filter is always powered from the control unit glow plugs, if you have a problem with them, you can turn on the light inside the glow plugs and give you the error in diagnosis.

[gero]

but to exclude it to a system?or to control it?
